Capsule for flanged cork stopper, capsulated stopper comprising said capsule and production process of the capsulated stopper

Abstract

The invention relates to a capsule (1) for a flanged cork stopper, the capsule (1) having a body (2) comprising a top (3) and a cavity (4) inside which at least two anti-rotation splines (5) are arranged, and the capsule further comprising an axial retention chamber (6) disposed within said cavity (4), wherein retention chamber (6) is shaped to receive and axially retain a flange of a flanged cork stopper. The invention also relates to a capsulated stopper comprising a flanged stopper, the flange of which is attached to the capsule (1) of the invention. The invention further relates to the production process of said capsulated stopper.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a capsule to be attached to a cork stopper having a flange. The invention further relates to a capsulated stopper comprising said capsule and the capsulated stopper production process.BACKGROUND OF THE INVENTION[0002]Cork stoppers to cap or seal containers, in particular wine bottles, are used since the 18th century, and are widely distributed through the market. In general, there were no alternative to cork stoppers until sealing caps of plastic material emerge in the mid-90s of the twentieth century.[0003]In yet another group, there are found stoppers generally used in bottles of spirit drinks, known as “Bartop” stoppers, which have a cork body and a capsule which is generally of another material, such as plastic, glass or wood.[0004]“Bartop” stoppers are essentially used for the purpose of capping the container, which is why they are not normally usable in still wine bottling, which requires higher sealing levels than t...

AI Technical Summary

Benefits of technology

This patent is about a capsule for a flanged cork stopper. The capsule has an internal cavity with at least two anti-rotation splines arranged inside it. The capsule also has an axial retention chamber that can hold the fl MariagEts the technical effects of the invention. The capsule can be used in containers such as bottles and is attached to the flange of a cork stopper using the anti-rotation splines. The process for producing the capsulated stopper involves placing the flange of the cork stopper into the axial retention chamber of the capsule. Overall, this invention provides a simple and efficient solution for attaching a cork stopper to a container and ensuring stability and sealing.

Problems solved by technology

“Bartop” stoppers are essentially used for the purpose of capping the container, which is why they are not normally usable in still wine bottling, which requires higher sealing levels than those provided by these stoppers.

The use of adhesives for attaching the cylindrical body of cork to the capsule has already proven to be an effective method under certain conditions of use but under extreme conditions it is found that its effectiveness may be compromised.

In fact, for very high temperatures and humidity, for example, the most common adhesives lose adhesion, causing peeling off or defects to occur in the final product.

On the other hand, if one wishes to use “Bartop” stoppers in still wines and taking into account how the latter are accommodated (stored in lying down bottles), there is a probability of the occurrence of liquid absorption phenomena through the stopper, and consequently the direct contact of the wine with the adhesive of the capsulated stopper.

Although the adhesives are food grade and not constitute any risk to the consumer, this situation is not desirable as the sensory quality of the wine sealed by these stoppers may be adulterated.

Furthermore, the use of adhesive for attaching the cylindrical body of cork to the capsule also limits the range of coatings and / or surface treatments to be applied on said cork body.
